Three months after the birth of his twins with Sally, Sonic finds himself returning to combat alongside Code Red and the rest of his friends as they fight to finally liberate Mobius from the brutal yoke of those that have subjugated it for so long. Sonic longs to end the war so that his family can at last be safe, but he should know by now: such things are easier said than done.

Joy and anticipation run rampant in Knothole as the village prepares for a life-changing event. However, the Decepticons and Robotnik have been making preparations of their own, hiring a ruthless mercenary to help them deal the final defeat to the Autobots and the Freeedom Fighters.

After Sonic finally proposes, things are looking up for the Knothole Freedom Fighters and Autobots. But when Code Red is critically wounded and left fighting for his life, things take a turn for the worst. Little do the Freedom Fighters know that the Decepticons and Robotnik have been planning a new malign plot, one they hope will spell certain doom for the Freedom Fighters...

Five months after the events of Project: Resurrection, the Freedom Fighters and Autobots are in a pitiful state. But after they make a startling discovery, they find a perfect opportunity to gain a foothold in their struggle against Dr Robotnik and the Decepticons.

As Code Red grieves over the loss of Ironhide, Sally, Tails, and Side-Arm attempt to find a means to lift his spirits. But what they find is something that will either break Code Red's spirit completely, or make him stronger than ever.

On a routine raid, the team discover a terrifying new weapon that Dr Robotnik is developing. With this dark threat looming, the Autobots and the Freedom Fighters face a race against time to prevent Robotnik's malign scheme from coming to fruition.

Sonic, Tails, and Knuckles team up with the now revived Optimus Prime and the Autobots to stop Eggman, Megatron, and the Decepticons from in an all new war. As they earn new powers and allies to retrieve a dispersed Allspark and the powerful seven Chaos Emeralds, Sonic, Tails and Knuckles learn that, like the Autobots, there is more to themselves than meets the eye.

"Is this truly how far he will go in his lust for power? To try and resurrect his armies?" "Yes, but it may be worse than that. He may go as far as to try to recreate the cube." "The cube is older than Cybertron itself. There is no way he could" "He has found a new power. One that may make it possible. And now, he drags a new planet and its people into the crossfire."

In a time when autobots were plentiful, a great war outbroke over control of the allspark, a great energy source. But only two sides of the story are told. A great bot named Ordonitron leads the neutral bots to freedom on a peaceful planet. But this planet has a secret lots of power hungry people would love to get their hands on...
